Determine the appropriate sample size using G*power for a study that will employ independent sample t-test, level of significance (alpha) = 0.05, power = 0.80, and using the three levels of effect size a. for small effect size, use 0.20 b. for medium effect size, use 0.50 c. for large effect size, use 0.80 Answer the following questions:1. Which of the obtained values would you recommend? Explain why? 2. Why is it important that researchers determine appropriate sample size with consideration to the level of significance, effect size, and power?

The gas mileage for a 2020 Toyota Prius hybrid vehicle is skewed to the left, with μ = 55 miles per gallon and o = 8 miles per gallon. Suppose a random sample of n = 16 will be selected, the gas mileage will be recorded for each Toyota Prius, and the sample mean will be computed. Based on the information provided, which option applies to the distribution of possible sample mean values? The distribution of all possible sample mean values is normal because the population distribution of responses is normal. The distribution of all possible sample mean values is unknown because the sample size is not large enough and the population distribution of responses is not normal. The distribution of all possible sample mean values is approximately normal because the sample size n is large enough (at least 10 successes and at least 10 failures). The distribution of all possible sample mean values is approximately normal because the sample size n is large enough (larger than 25).
